The present invention relates to locking devices and in the particular embodiments disclosed herein, provides locking devices of the ,so-

called rotary bolt type'especi-ally designed for automotive use.

The principal objects of the present invention are to provide a locking device, including a bolt cooper-able with an associated keeper, means for effecting a release of the bolt, and control means selectively operable to render the releasing means eiiective'and ineffective; .to provide such a structure wherein the bolt is of the so-called rotary type, having cam means associated therewith to hold the bolt in a locking position, and wherein the bolt is released by retracting the cam means from cooperative relation therewith; to provide such a structure wherein the retracting means includes elements operable from without and within the door, and wherein the control means may be selectively operated to render either or both of the retracting means inefiective; to provide such structure including a retracting member, and a control means operable to a locking position for rendering the retracting member ineffective to release the bolt, the arrangement being such that a closing of the associated door while the control means is set to locking position normally restores the retracting member to effective condition, but wherein, by suitable manipulation of the retracting member, such closure does not so restore the retracting member; to provide such a structure wherein the locking means controls the retracting members associated with both the inside handle and the outside handle so that the same may be set when the door is closed to prevent the release of the bolt from either the inside or the outside of the door; I

to provide such a structure wherein the control means affects only the outside operated retracting member, so that the inside operated retracting member remain-s continuously effective to effect an opening movement of the door; and to provide structures of the above generally described type, including improved arrangements and relationships of the parts so as to provide extremely simple, eii'ective, and reliable locking devices.

With the above as well as other objects in view, which appear in the-following description and in the appended claims, preferred but illustrative embodiments of the invention are shown in the accompanying drawings, throughout the several views of which corresponding reference characters are used to designate corresponding parts, and wherein:

Referring first to Figs. 1 through 8, the herein illustrated embodiment of the invention comprises generally a bolt 20 of the rotary type, ar rangedfor cooperation with an associated keeper 22; a series of holding cams 24, which function to urge the bolt into engagement with the keeper '22 so as to hold the associated door in closed position; a retracting member 26, which may be actuated either by the outside operated roll-back 28, or by the inside operated lever 30; and a locking control member designated as a whole as 32, which, as hereinafter described, may be actuated to render both the outside operated rollback 28' and the inside operated lever 30 ineffective to cause a release of the bolt 20.

The above enumerated elements are carried clearly appears in Fig. 2, with the. flange 38' thereof in abutting relation to the rail 42 of along and generally parallel to the inner panel of the door, the relation being such that the keeper engaging portion of the bolt2llprojects outwardly from the rail of the door, for cooperation with the previouslymentioned keeper 22.

The construction and the arrangement of the bolt 26, the keeper 22, and the holding cams 24,

is substantially the same as that in applicants copending application Serial No. 159,746, filed August 18, 1-937, and assigned to the same assignee of the present application. These elements and their relation to the case plate 34 will, therefore, require only a brief description.

As clearly appears in Figs. 3, 4, and 6, the bolt 20 comprises a series dinner or cam engaging teeth 20a and a series of outer or keeper engaging teeth 20b, which are separated by a dividin fin 44. The bolt 20 is rotatably carried upon a pin 46, the inner end whereof is journalled in a supplemental case plate member 48 which is secured in inwardly spaced relation to the flange 38 of the case plate. The other end of the pin 46 is secured in a housing-like member 60 which projects from the rail 42 of the door and encloses the lower portion of the keeper engaging parts of the bolt 26. The flange 38 of the case plate 34 is provided with an opening 62 to receive the bolt 20, and it will be understood that the rail of the door is provided with a corresponding opening so as to permit the housing member 50 and the keeper engaging parts of the bolt to project'outw-ardly from the rail of the door.

The holding cams, designated as a wholeas 24, comprise a series of three progressively dimensioned cams or dogs 24a, 24b, and 240, which are pivotally mounted upon a pin 64 common thereto. One end of the pin 64 is joumaled in the previously mentioned supplemental case plate member 48 and the other end thereof is supported in an abutment member 56, which projects outwardly from the rail of the door in upwardly spaced relation to the bolt.

The cams 24a, 24b, and 240 are continuously urged in a counterclockwise direction of rotation by springs 58a, 58b, and 560 individual thereto, respectively, which springs are secured to the flange of the case plate 34, and are positioned between such flange and the supplemental hous ing member 48. The springs cause the feet of the cams to bear upon the back, such as 20a, of one of the teeth 20a of the bolt 20,-and by this bearing action, continuously urge the bolt 20 in a counterclockwise direction of rotation as viewed in Figs. 3 and 4. It will be noted that this counterclockwise direction of rotation urges the keeper-engaging teeth 20b of the bolt 20 into abutting relation to the face 22a of the keeper 22. This action continuously urges the door 40 in a closing direction relative to the associated vehicle pillar, and also applies a vertical component of force between the bolt 20 and the keeper 22, which wedges the latter between the bolt 26 and the previously mentioned abutment 56. It will thus be observed that the locking device also functions as a door dovetail, so as to prevent rattling movements of the door.

In order to provide for the retraction of the cams 24, so as to permit an opening movement of the door, as described below, the shortest cam 240 is provided with a laterally turned flange 66, which lies behind the other cams 24a and 24b, and is also provided with a foot 62 which lies in the path of movement of the nose 64 of the previously mentioned retracting member 26.

the door, and with the base 36 thereof extending As is described below, an unlatching operation, initiated either by the inside handle or the outside handle, results in a downward movement of the nose 64, as viewed in Fig. 5. This downward movement causes .a corresponding movement of the foot 62, and swings the cams 24 in a clockwise direction, as viewed in Figs. 3 and 4. This clockwise movement, which is resisted by the associated springs, swings the cams 24 from the locking positions shown in Fig. 3, through the partially retracted positions shown in Fig. 5, to the fully retracted positions in which they are out of engagement with the teeth a of the bolt 20. With the cams 24 thus retracted, the bolt 20 may be freely rotated in a clockwise direction, as viewed in Figs. 3, 4 and 5, thusperteeth 26b roll over the projection 22b of the mitting the door to be freely opened. During the coursev of the door opening movement, the bolt keeper, and the safety catch 66 thereof, much in the manner of a gear rolling along a rack. As soon as the door has been opened sufiiciently far so that the bolt 20 clears the keeper 22, the retracting nose 64 may of course be released to its elevated position shown in Fig. 5, enabling the springs 53a, 58b, and 680 to return the cams 24 to the locking position shown in Fig. 3.

The door may, of course, be closed without manually operating the retracting nose 64. During the course of such closing movement, one of the teeth 20b of the bolt 20 engages the safety catch 66 associated with the keeper 22. The latter is yieldable, so that the continued door closing movement enables such tooth to cam the safety catch 66 to a retracted position, without involving a rotation of the bolt 20. As soon as the just mentioned tooth 20b passes beyond the safety catch 66, the latter is enabled to return to the projected position shown in Fig. 4, at which time the tooth 20b occupies a position between the end of the safety catch and the keeper nose 22b. With the parts thus positioned, the keeper 22 is enabled to hold the door in the partially closed safety position, since a withdrawal from such position would involve a rotation of the bolt in a clockwise direction, which rotation is prevented by the cams 24, as clearly appears in Fig. 3.

If the door closing movement is continued beyond the just mentioned safety position, the previously mentioned tooth 20b of the keeper 26 engages the forward face of the nose 22b of the keeper 22. The latter nose is rigid and, consequently, continued door closing movement causes a rotation ofthe bolt 20 in a counterclockwise direction, as viewed in Figs. 3, 4, and 5. During this movement, a face such as 20a" of one of the cam engaging teeth 20a of the bolt bears against the heels of the cams 24, and forcibly rotates the latter in a clockwise direction, as viewed in Figs.

3 and 5, from thelocking position shown in Fig. 3 to the partially retracted position shown in Fig. 5. During the course of this retracting movement, the surface 20a" of the bolt 20 passes beyond the heel of the shortest cam 24c, enabling the spring associated with the latter to force it in a counterclockwise direction towards the position shown in' Fig. 3. During this rotation, the cam 24c applies a rotative force to the bolt 20 in a counterclockwise direction, thus assisting the door closing movement. A continued counterclockwise rotation of the bolt 26 brings the surface 20a" thereof successively beyond the heels of the longer cams 24b and 24a, enabling the latter to swing, under the influence of their springs, towards the fully locked positions shown in Fig. 3, which and urges the door to and tightly holds it in a fully closed position. As the cams 24 swing towards the fully closed position, they assume positions in full blocking relation to th bolt 20, and thus become effective to positively prevent a to cause a downward orretracting movement of the foot 62 associated with the cam 24, comprises clockwise or door opening movement of the bolt 20. The locking device thus functions to positively hold the door against an opening movement and at the same time, functions to urge the door continuously towards a more tightly closed position.

Turning now to Figs. 7 and 8, it will be noted that the retracting member 26 is in the general form of a slidable link, the lower end whereof is provided with a laterally turned foot 80, which lies in the path of the nose 28a of the outside operated rollback 28. The upper end of the retracting member 26 is widened and is also provided with the previously mentioned nose 64 for cooperation with the foot 62 associated with the cam 24. The central part of the widened upper end of the retracting member 26 is cut away to provide an opening, having spaced arcuate seats 82 and 84 at the base thereof, and having spaced arcuate seats 86 and 88 at the upper end thereof. The seats 86 and 68 are separated by a downwardly projecting finger 90, the purpose of which is described hereinafter.

The retracting member 26 is guided relative to the case plate by a pin 92, the locking memher 32, and by a housing associated with the lower end of member 26. One end of pin 92 is secured to the flange 36 of the case plate 34 and the other end thereof is provided with an enlarged head or washer 94, as clearly appears in Fig. 2, which bears against the back of the inside link 30. Pin -94 thus holds members 26, 30, and 32 in slidablembutting relation to each other.

It will be noticed by comparison of Figs. '7 and 8, that the retracting member 26 is movable between a normal or efiective position shown in Fig. 7 and an ineffective position, shown. in Fig. 8. Inv the former position, the pin 92 occupies the seat 82 and in the latter position, the pin 92 occupies the seat 84. By virtue of the upward bias of the spring I00, the member 26 is releasably held in either of the above two positions, as will be evident. The movement ofthe member 26 between the efiective and ineffective positions is controlled by the locking member 32 as described below.

The above mentioned housing for the lower end of member 26 is provided by the two side walls 96 and 98 of a supplemental casing element which is secured to the case plate adjacent the lower end thereof as appears in Fig. 3. The just mentioned supplemental casing also houses a compression spring I00, which bears against the previously mentioned foot 80 on the slide 26, and continuously urges the latter upwardly to the position shown in Fig. 7.

The inside retracting lever is pivotally mounted on the previously mentioned pin 92, and adjacent its upper end, is provided with a laterally turned foot I02 which overlies the nose 64 of the retracting member 26. The lower end of the lever 30 is provided with an opening I04, by which it may be connected to suitable mechanism responsive to the inside handle (not shown) as will be understood, and such mechanism, as is conventional, is preferably arranged to include means to yieldablybias the lever 30 to the angular position shown in Figs. '7 and 8.

In the illustrated instance, the means for rendering movements of the member 26 ineffective a generally triangular plate 32, which is pivotally -mounted upon the case plate by means of the previously mentionedpin 62, and which is provided with a generally triangular opening I08 in the body thereof, which is adapted to receive a laterally turned foot IIO formed on the retracting member 26. The locking member 32 is arranged for operation between the normal unlocked position shown in Fig. 7 and the locked position shown in Fig. 8, by means of a push rod I06 which is connected thereto adjacent one corner thereof and which extends upwardly through the garnish molding of the associated door and is provided at its 'upper end with a control button II2, as most clearly appears in Fig. 1. In order to releasably hold it in either the locked or the unlocked position, the locking member 32 is provided with a toggle spring II3, one end II3a whereof is hooked in the base 36 of the case plate (Figs. 3 and 16) and the other end II3b whereof is passed through the flange I I4 of the locking member 32. It is noted that spring II3 passes an over-center position during movement of locking member 32 between the positions shown in Figs. 7 and 8.

With the foregoing general description in mind, it will be appreciated that when the door is in the fully closed position and when the locking member 32 is in the unlocked position, the parts occupythe positions shown in Figs. 1, 2, 3, 4, and 7, in which positions the cams 24 are in holding relation to the bolt 20 and so prevent a clockwise or door opening movement thereof. With the parts thus positioned, the door may be unlatched and moved to an open position, by operating either the outside rollback 28, or by operating the inside lever 30. Assuming the rollback is operated, by means of the outside handle II8, the nose 28a thereof is forced downwardly against the foot 80 on the retracting member 26, forcing the latter downwardly against the force of the compression spring I00 associated therewith. The downward movement of the retracting member 26 brings the foot 64 formed thereon into abutting relation with the foot 62 associated with the cams 24, causing a downward movement of the latter. This latter downward movement, as previouly described, retracts the cams to the full retracted positions, permitting the door to be moved to the open position. A corresponding action results from a rotation in a clockwise direction of the lever 30, which action brings the foot I02 associated therewith downwardly into abutting relation with the foot 64 formed on the retracting member 26 and again forcing the latter retracted positions shown in Fig.5, by the cooperation between the keeper and the bolt. This action, However, simply moves the foot 62 associated with the cams 24 downwardly, away from the retracting member 26, without otherwise altering the positioning of the parts as shown in Fig. 7. w

As previously mentioned, when the retracting member 26 is in its uppermost position shown in of the foot 62 associated with the cams 24.

Fig. 7, the pin 32 occupies the lefthand seat 62,

under the influence of the spring I88, and releasably holds the retracting link 26 in its righthand or effective position. During the downward movement of the member 26 incident to an operation of the rollback 26 or the lever 38, the seat 82 moves away from the pin 92, so that the just mentioned releasable holding action no longer obtains. However, during the course of this downward movement, the foot I I8 associated with the member 26 rides between the portions I88a and I88b oi the previously mentioned opening I88 in the locking member 32. This action guides the retracting member 26 vertically downwardly until such time as the lower end of the finger 98, associated with the member 26, passes slightly below and to the right of the pin 62 as viewed in Fig. 7. Following this action, the pin again positively cooperates with the retracting member 26 to guide the movements of the upper end of the latter. Thus, under normal operating conditions, the retracting member 26 moves between the normal position thereof shown in Fig. 'l and a lower position, in which the pin 82 cupies the seat 86.

Assuming it is desired to render the inside and outside handles ineffective to unlock the door,

the button II2 (Fig. 1) may be manually depressed, which action, through the push rod I86, swings the locking member .32 from the position shown in Fig. '7 to the positionshown in Fig. 8. During this swinging movement, the marginal portion I88b of the opening I88 in the locking member 32 bears against the foot II8 formed on the retracting member 26 and cams the latter from the position shown in Fig. '7 to the position shown in Fig. 8. It will be appreciated that in the latter position, the pin 32 occupies the righthand seat 84, instead of the lefthand seat 62, as previously described. During the course of the just mentioned swinging movement of the retracted member 26, it is forced downwardly slightly against the force of the compression spring I88 so as to accommodate the passage of the dwell 26a past the pin 92. I

When the retracting member 26 is swung to position shown in Fig. 8, however, brings the nose I28 to a position immediately below and in the path of the foot 62. With this relation, it will over-center spring II3 associated therewith bethe position shown in Fig. 8, the foot 64 asso ciated therewith moves to a position to the left of the foot 62 associated with the retracting cams 24, so that a downward movement of the retracting member 26 under the influence of the outside rollback 28, causes the foot 64 to move idly by the foot 62. Similarly, the foot 64 passes out of the path of the foot I82 associated with the inside link 38, so that the swinging movement of th latter is inefiective to-retract the cams 24. Accordingly, it will be understood that so long as the locking member 32 occupies the locking position shown in Fig. 8, the inside and outside retracting mechanisms are freely movable by means of their associated handles, but that such movements thereof are ineffective to retract the cams 24 and release the door.

From time to time, the locking member 32 may be moved to the locking position at the time when the door is open, and it is desirable to provide thatunder these conditions, the closing of the door normally restores the parts to the unlocked positions. In the present arrangement, this is accomplished by providing the locking member 32 with a nose I28 which, in the normal position of the parts (Fig. '7) occupies a position out of the range of downward movement The movement of the locking member 32 to the locked comes effective to again hold the locking member 32 in the unlocked position. The movement of the locking member 32, through the engagement of the edge I88a of the opening I88 with the foot II8, also swings the retracting member 26 to its normal or effective position.

A feature of the present invention resides in arranging the structure so as to Permit the door to be closedwithout restoring the locking member 32 to the unlocked position. In the present instance, this is accomplished by holding the outside handle H8 in its bolt retracted position during the closing of the door. For example, assuming the door is moved to the open position, and that thereafter the locking member 32 is moved to the locked position, the parts in question assume the positions shown in Fig. 8. If the outside handle I I6 is now moved to the retracted position, the rollback 28 moves counterclockwise and forces the retracting member 26 downwardly to a position in which the pin 92 occupies the seat 88. This downward movement of the retracting member 26 brings the foot II8 thereof out of the restricted space between the marginal portions I88a and I 88b into the enlarged central part of the opening I88. If the door is now closed, the foot 62 associated with the cams 24 again moves downwardly. and, by engagement with the nose I 28 of the locking member 32, again swings the latter in a clockwise direction from the locking position shown in Fig. 8 to the unlocked position shown in Fig. 7. This movement of the locking member 32, however, is ineifective to restore the retracting member 26 to the normal position shown in Fig. 7, since the latter is positively held in the lefthand position shown in Fig. 8 by the pin 92, which now occupies the seat 88.

It is noted that during the course of the Just mentioned downward movement of the retracting member 26, as influenced by the rollback 28 the seat 84 moves away from the pin 92, render: ing the latter no longer efiective to yieldingly hold the retracting member 26 in the lefthand position. Until such a time, however, as the lower end of the finger 98 moves down suinciently far so as to positively introduce the pin 32 into the seat 88, the foot H8 01 the retracting member 26 is guided between the marginal edges I88a and I881). which latter edge particularly prevents the retracting member 26 from swinging to the right to its normal or eifective position.

If the outside rollback 26 is now released by releasing the outside handle, the foot II8 associated with the retracting member 26 is'again effective to force the latter upwardly. Under the conditions in question, the foot I I8 bears against the sloping marginal edgel88c of the opening I88 in the locking member 32 and during the upward movement of the member 26 i thus effective to cam the locking member 32 from the unlocked position shown in Fig. 7 to the locked posimal position. Such swinging, however, is initially prevented by the finger 80 bearing on the pin 92. Before the lower end of thefinger 60 edge I081) of the opening I08. As soon as this action occurs, the foot I I and the marginal edge I08b become effective to prevent a rightward swinging movement of the retracting member 26.

When the seat 84 engagas the pin .92, the latter becomes effective to hold the retracting member 26 in the lefthand ineffective position, a previously described.

The parts may, of course, be restored to normal unlocked condition again by manually oper-- ating the push button II2 to lift rod 106 and swing member 32 to its unlocked position.

' The embodiment shown in Figs. 9 and. 10 distinguishes functionally from the previously described embodiment in that the arrangement is such that the inside handle mechanism remains continuously effective to retract the holding cams 24 and thus effect an opening of the door, and distinguishes structurally in respect to the form of the locking member and the form of the retracting member. the retracting member I 50, which corresponds generally to the previously described retracting member 26, is slidably mounted adjacent the base of the associated case plate, the lower end thereof being arranged for cooperation with the rollback 28 in the previously described manner, and also being provided with a compression spring I00 for urging the retracting member upwardly. The upper end of the retracting member I50 is widened and is provided with an opening I52, which affords seats 82, 84, 86, and 88 corresponding in arrangement and function to the previously described seats in the retracting member 26. The extreme upper end of the retracting member I50 is provided with spaced shoulders I54 and I56, which receive between them a laterally turned foot I58 associated with the gen- Referring to Figs. 9 and 10,

position of the retracting member I50. .It will be understood, accordingly,that the locking member I60 serves only to render the outside handle mechanism ineffective and does not interfere in any way with the normal operation of the inside handle mechanism. As in the previous instance, the lever I66 may be conventionally connected to suitable inside handle mechanism (not shown).

Considering now the guiding action between the retracting member I50 and the locking member I60, it is noted that when the parts are in the position shown in Fig. 9, the pin I62 exerts a holding action on the retracting member I50 and yieldingly holds the latter in its eifective or righthand position. During a downward movement of the retracting member I50, as influenced by the rollback 28, the seat 82 moves away from the pin I62 rendering the latter ineffective to. exert the yieldable holding action. Until such time, however, as the finger 90 associated with the retracting member I50 moves to a position in blocking relation on the righthand side of the pin I62, the foot I58 associated with the locking member I60 lies in blocking relation to the shoulder I56 associated with the retracting member I50 and thus prevents the latter fromswinging to the left to its ineffective poslretracting member-l50 is guided in such a way as to be retained in its so-called effective condierally triangularly formed locking member I60.

The locking member I60 is pivotally mounted upon a' pin I62, corresponding to the previously mentioned pin 92, and is arranged for operation by means of a push rod I06. As in the previous instance, also, the locking member I60 is provided with over-center spring mechanism II3, which is connected between the locking member and the case plate, and is arranged to hold the locking member I60 in either the unlocked position shown in Fig. 9 or in the locked position shown in FigrlO.

, The retracting member I is provided with a nose I66 which, as in the previous instance, is positioned directly above the foot 62 associated with the retracting cams 24. With this relation, it will be understood that a downward movement of the retracting member I50 as effected by the outside rollback 28, causes a downward or retracting movement of the foot 62 in the previously described manner and thus releases the cams and enables the door to be opened. In this instance, the inside operated mechanism comprises a lever I66 which is pivotally mounted upon the pin I62, and which is provided with a-n'ose I68, which is-positioned for direct engagement with the foot 62. With this relation, accordingly, an opening movement of the door can be eifected by swinging the lever I66 independently of the tlon. I

Assuming that it is desired to render the outside handle mechanism ineffective, the locking 'member- I60 may be swung from the position shown in Fig. 9 to the position shown in Fig. 10, during the course of which movement, the foot I58 associated therewith bears against the shoulder I54 associated with the retracting member I50 and swings the latter to the ineffective position in which it is yieldingly held by the seating of the pin I62 in the seat 84. When the retracting member I 50 is in the ineffective position shown in Fig. 10, the nose I64.thereof is out of range of the foot 62 associated with the cams 24, so that a downward or retracting movement of the retracting member I50 as influenced by the outside rollback 28, is ineffective to retract the cams.

v If the retracting member I50 is moved downwardly by operation of the outside handle while it occupies its ineffective position, it is guided and retained inthe ineifective position by the cooperation between the foot I58 and the shoulder I54 until such a time as the finger movesdownwardly to a. position to the left and in blocking relation to the pin I62.

As in. the previous embodiment, if the locking locking member I60 about its pivot, rendering the foot I58 thereof eifective to bear against the shoulder I 56 associated with the retracting member I50 and swings the latter from its ineffective position to its eifective position, in which position it is again yieldingly retained by the toggle action of the pin I62 and spring I00. i

If it is desired to effect the closing of the door without restoring the retracting member I50 to the effective position, the outside handle may be held in its retracted position as in the previous instance, which action rotates the rollback 26 in a counterclockwise direction and forces the retracting member I50 downwardly from the position shown in Fig. 10 to a position in which pin I62 occupies the seat 66. This downward movement of the retracting member I50 also brings the shoulder I56 downwardly out of range of the foot I58 formed on the locking member, so

' that the locking member I60 may freely swing to the unlocked position during the closing movement of the door, as influenced by-the engagement of the nose I10 thereof by the foot 62 associated with the locking cam 24, without affecting the position of the retracting member I 50. As soon as the door is fully closed, the outside handle may be released, enabling the spring I to move the retracting member I50 upwardly to the position shown in Fig. 10. At the time this movement is begun. the foot I58 associated with the locking member I60 lies above and in the path of the shoulder I56. The upward movement of the retracting member I50-thus renders the shoulder I56 effective to engage the foot I56 and rock the locking member I60 about its pivot point, restoring the locking member I60 to the locked position shown in Fig. 10. During the initial part of the return movement of the retracting member, the latter is held'in its ineffective position by the cooperation between the finger 90 and the pin I62. Prior to the time that the finger 90 passes above and out of range of pin I62, the shoulder I56 on the retracting member I50 passes to the left of the foot I56 on the locking member. At this time, the locking member is yieldably held in its locked position by its associated toggle mechanism, and such shoulder I 54 and foot I56, therefore, cooperate to hold the retracting member I 50 in its ineffective position until such time as the pin I62 again seats in the seat 64.

'Except in the respects specifically described above, the embodiment of Figs. 9 and 10 may, and preferably does, correspond in all respects to the embodiment described with reference to Figs. 1 through 8. It is thought, therefore, that a further description of the embodiment of Figs. 9 and 10 is unnecessary.

Referring particularly to Figs. 11 and 12, an embodiment of the invention is disclosed wherein the construction and arrangement correspond in all respects to the construction and arrangement described with reference to Figs. 9 and 10, with the exception that the locking member I may be moved to locked position, either by means of the previously mentioned push rod I06, which is operable from within the vehicle. or by means of an outside operated key mechanism. In this instance, the locking member I60 is provided with an offset foot I90, which is received between the legs I92 and I9! of a key operated link I96, which is pivotally mounted upon the lock mechanism by means of a pin I96. The link I96 is received between the locking member I60 and the offset lower portion of the retracting member I50.

In this instance, the key operated link I96 is arranged for operation by a conventional key cylinder positioned within the handle of the door. In the illustrated instance, the spindle 200 is of tubular form, and receives a locking cylinder through a angle from the position shown in Fig. 11, in a counterclockwise direction, is effective to force the pin 202 upwardly into engagement with a foot 2I0 formed at the lower end of the key link I96. This action rocks the latter in a counterclockwise direction about its pivot pin I 96, and, through the foot I 90, swings the locking member I60 from the locked position shown in Fig. 11 to theunlocked position shown in Fig. 12. On the other hand, when the key operated link I96 is in its unlocked position. shown in Fig. 12, the key cylinder may be rotated 90 in a clockwise direction, as viewed in Fig. 12, forcing the pin 202 downwardly, and rotating the key operated link I96 in a clockwise direction. This action, through the foot I90, rocks the locking member I60 from the unlocked position to the locked position. It' will be understood that the movement of the locking member between the locked and unlocked positions causes corresponding movements of the retracting member I60.

Key cylinder constructions of this kind contemplated herein conventionally include means, such as a spring, to return the key cylinder to the normal position upon release of the key. It will be understood also, that, although a specific cylinder operated mechanism has been described, any suitable key cylinder type of lock may be utilized, the fundamental relation being one wherein a locking movement of the key forces the link I96 in the locking direction and an unlocking movement of the key forces the link I96 copy the unlocked position shown in Fig. 14,

wherein the pin 2I8 is seated against the upper end of the slot 220 and in which the locking member I60 occupies its normal unlocked position. With the parts in this position, a rotation of the key spindle 2I2 in a counterclockwise direction causes corresponding movement of the link 2I6, and causes a downward movement of the link 2. Since the pin 2I6 normally bears against the upper end of the slot 220, the movement of the link 2 causes a counterclockwise or looking movement of the locking member I60. On the other hand, since the pin 2| 6 has a lost motion connection with the link 2I6, it will be understood that the locking member I60 may be moved to the locking position by means of the push rod I06 for example, without altering the position of the key operated links 2 and H6, the length of the slot 220 being such that after the link 2I6has been actuated to move the looking member I60 to the locked position shown in I Fig. 13, the links may be restored to the posirection from the position shown in Fig. 14,.which action brings the lower end of the slot 220 in fective to restore the locking member I60 to the "Min unlocked position. v

In all respects except those noted above the embodiments of Figs. 11, 12, 13, 14, and 15 may and preferably do correspondin all respects to the previously described embodiments andit is thought, therefore, that a further description is unnecessary,

Although only several specific embodiments of the invention have been described in detail herein, it will be appreciated that further modifications of the invention may be made without departing from the spirit and scope of the invention.
